In the olden days, castles were built in order to protect against invading armies and barbarians. The modern Wisconsin castle is usually built as a means of showing off. This modern castle, however, looks like it exists more to fulfill the former purpose. The exterior is concrete and spare, with abundant battlements and not much else. Invade this home at your own peril, or you can just buy it for $1.5 million.
